suppose fourth angle of a quadrilateral=x
100+50+50+x=360(sum of all angles of
quadrilateral is 360)
200+x=360
x=360-200
x=160 degree
so the measure of the fourth angle of a quadrilateral is 160 degree
100+50+50+x=360(sum of all angles of
quadrilateral is 360)
200+x=360
x=360-200
x=160 degree
so the measure of the fourth angle of a quadrilateral is 160 degree
